2 results about "Panicum miliaceum" patented technology

Panicum miliaceum is a grain crop with many common names including proso millet, broomcorn millet, common millet,, hog millet, Kashfi millet red millet, and white millet. Archeological evidence suggests that the crop was first domesticated before 10,000 BCE in Northern China. The crop is extensively cultivated in China, India, Nepal, Russia, Ukraine, Belarus, the Middle East, Turkey, Romania, and the United States, where approximately half a million acres are grown each year. The crop is notable both for its extremely short lifespan, with some varieties producing grain only 60 days after planting, and its low water requirements, producing grain more efficiently per unit of moisture than any other grain species tested. The name "proso millet" comes from the pan-Slavic general and generic name for millet (Croatian: proso). Proso millet is a relative of foxtail millet, pearl millet, maize, and sorghum within the grass sub-family Panicoideae. While all of these crops utilize C4 photosynthesis, the others all employ the NADP-ME as their primary carbon shuttle pathway while the primary C4 carbon shuttle in proso millet is the NAD-ME pathway.

A rotary tillage and fertilizer device for seeding proso millet

The utility model relates to agricultural machinery technical field, the utility model provides a kind of millet sowing rotary tillage fertilizer device, including rotary tillage frame, the bottom of rotary tillage frame is rotatably connected with rotary tillage axle rod, the utility model is provided with sliding plate and cleaning plate by being set in the bottom of rotary tillage frame, operator can clean rotary tillage blade by cleaning plate intermittent sliding when rotating rotary tillage axle rod and carrying out rotary tillage, rotary tillage axle rotates and will drive rotary disc to carry out circumferential rotation, rotary disc will promote sliding wheel to carry out reciprocating horizontal sliding when circumferential rotation, sliding wheel then promotes push rod and push block to carry out reciprocating sliding, then push block will promote sliding plate to slide, sliding plate is finally rebounded to original position by the elastic force of spring rod, under the intermotion of spring rod and push rod, realize the reciprocating sliding of cleaning plate and steel wire brush, and the surface of rotary tillage blade is intermittently cleaned by the reciprocating sliding of cleaning plate and steel wire brush.

Codominant molecular marker method developed based on broom corn millet regulatory gene Hd1

The invention belongs to the technical field of crop genetic breeding, and particularly relates to a broomcorn millet regulatory gene Hd1 development-based codominant molecular marking method, which comprises the following specific steps: acquiring an Hd1 gene sequence of a paddy rice related species from an NCBI database, comparing BLAST with a broomcorn millet reference genome, positioning a broomcorn millet Hd1 homologous region, and identifying the broomcorn millet regulatory gene Hd1 homologous region. By sequencing Hd1 genes of 20-30 parts of broom corn millet varieties, combining with generic genome data, identifying low-frequency PAVs and TE derivative variation, supplementing the defects of traditional SNP / InDel, preferentially developing markers of a coding region and a promoter region, and directly influencing gene functions by variation of the regions, the polymorphism detection efficiency is improved; cross-species verification is carried out by using Hd1 markers of related species such as rice and millet, a broom corn millet marker is rapidly developed by adjusting primers and amplification conditions, a differential expression region of Hd1 is identified through transcriptome sequencing, and an EST-SSR or InDel marker is designed.
